I have a 3750 with a gigabit rj45 SFP, and I am planning on connecting it to a gigabit port on a 6509 and running it at gigabit speed.
My questions are:
-do I need a crossover cable to do this?
-does it need to be a special cable for gigabit crossover?
-could I enable MDIX or will it not work because the 6509 will not support this?
Any help would be much appreciated!
MDIX will work if you leave the 3750 speed/duplex set as auto, it will not work if you attempt to use a hardcoded speed/duplex. Gigabit needs all 4 pairs to run gigabit speed so all 4 pairs must be ok. The 6509 end should also be set as auto.
